I lived that also--except for my engineering school, only one in four made it to graduation.
I made it, and then I found that my real education occurred after college.
Isn't that the truth!! I was scared wit-less at my first job, just waiting for someone to present me with an engineering problem, and have them realize I hadn't a clue as how to design anything. I could do matrix math, permutations, differential calculations, relativistic physics, express Reynolds Equations, and roughly explain Special Relativity.
But, connect a J-K Flip-Flop into a timing circuit?
However, to my school's credit; the assortment of tools and concepts I had learned really helped me absorb new material quickly, easily and orderly.
Agreed that the real education occurs after college. Problem is that far to many get out of college without the base skills to be truly educated.
